Abstract

The present invention is directed to a host device and an associated consumable item that electronically communicates with the device. Exchanged information between the device and attachment is used to prevent improper device operation, limiting injury and ensuring reliable and proper operation. Communication between the host device and consumable electrodes allow for the continuous monitoring and adjustment of therapeutic electrical signals, ensuring the accurate and safe delivery of therapeutic energy into deep tissue. Embodiments include consumable items that exchange information including a physical type, a status, and/or quality control standards of the consumable item. Embodiments include an assembly or group of consumables that can communicate among themselves and with a host device; performing fixed or varied tasks for one another and/or the host device. Embodiments of the consumable item include medical consumable items. Methods of operation thereof are also disclosed.

Claims

1. A method for managing use of a consumable item, the method comprising:

connecting a host device to the consumable item;

receiving status information from the consumable item at the host device, wherein the status information is based on an electrical property of the consumable item;

determining whether the consumable item is a valid item based on the status information received; and

permitting operation of the host device with the consumable item based on the determination whether the consumable item is a valid item.

2. The method of claim 1, further comprising rejecting the consumable item if the consumable item is an invalid item.

3. The method of claim 1, wherein the status information represents conductivity of the consumable item.

4. The method of claim 1, wherein the status information represents usage of the consumable item.

5. The method of claim 4, wherein the consumable item is validated if a usage limit is not exceeded.

6. The method of claim 5, wherein the usage limit is a number of uses.

7. The method of claim 5, wherein the usage limit is an amount of time of use.

8. The method of claim 1, wherein the status information represents a date of manufacture of the consumable item.

9. The method of claim 1, wherein the determination whether the consumable item is a valid item comprises checking a manufacturer'"'"'s code to ensure proper quality control standards are met.

10. The method of claim 3, wherein the status information represents a size of the consumable item.

11. The method of claim 1, further comprising adjusting the operation of the host device based on information supplied by the consumable item.

12. An intelligent consumable item comprising:

a microcontroller configured to communicate with a host device, comprising;

a writable memory;

a read-only memory; and

a communications transceiver; and

a device having an electrical property;

wherein the electrical property represents a status of the consumable item.

13. The intelligent consumable item of claim 12, wherein the electrical property represents usage of the consumable item.

14. The intelligent consumable item of claim 12, wherein the electrical property represents a conductivity of the consumable item.

15. The intelligent consumable item of claim 12, wherein information is stored in the consumable item and is communicated to the host device that represents a manufacture date of the consumable item.

16. The intelligent consumable item of claim 15, wherein the microcontroller is further configured to communicate information to another consumable item.

17. The intelligent consumable item of claim 12, further comprising a transducer for monitoring a physiological parameter.

18. The intelligent consumable item of claim 12, further comprising a gel-based electrode.

19. The intelligent consumable item of claim 12, further comprising a percutaneous electrode array.

20. A system for use with an intelligent consumable item, the system comprising:

a host device comprising a programmable interface controller;

a data transfer system; and

a consumable item comprising a memory,

wherein the programmable interface controller is configured to receive information stored in the memory of the consumable item via the data transfer system and to prevent use of the item if the information does not meet predetermined criteria.

21. The system of claim 20, wherein the programmable interface controller updates the memory in the consumable item based on a number of times the item has been used.

22. The system of claim 20, wherein the programmable interface controller adjusts operation of the host device based on the information stored by and received from the consumable item.

23. The system of claim 20, wherein the information stored in the memory of the consumable item indicates a status of the consumable item.

24. The system of claim 20, wherein the predetermined criteria include usage criteria.

25. The system of claim 20, wherein the predetermined criteria include characteristics of the consumable item.
